Abstract

The invention, which belongs to the field of brain-computer interfaces, relates to a motion-imagination-based portable brain-controlled unmanned aerial vehicle system and a control method thereof. Thesystem is composed of an EEG signal acquisition device, an embedded EEG signal processing device, and a flight portion. The EEG signal acquisition device uses a high-precision and high-integration analog front end and a high-precision and high-integration AD conversion chip, so that power consumption of the EEG signal acquisition module is reduced, the system design is simplified, and the signal-to-noise ratio is improved; and signal processing is carried out well and thus the size of the EEG signal acquisition device is reduced substantially. According to the system, the EEG signal acquisition device is installed at an occipital lobe part of an electrode cap in an integration manner and the bluetooth is used as a data transmission mode, so that the collection part of the EEG signal is combined with the electrode cap and an independent part is formed. Therefore, the comfort and flexibility of the user are improved substantially.

Description

technical field [0001] The invention belongs to the field of brain-computer interface, and relates to a portable brain-controlled unmanned aerial vehicle system and control method based on motor imagination. Background technique [0002] Brain-computer interface (Brain-computer interface, BCI) establishes a communication and control channel between human and computer. A system of communication between the human brain and a computer or other electronic device. This technology can help disabled people with motor disabilities to control the external environment and equipment, and improve their self-care ability. Studies have shown that specific imaginative tasks can generate specific EEG signals, such as imagining movement on one side of a limb, which can cause synchronous weakening or strengthening of certain components of EEG signals in the opposite side of the brain. This phenomenon is called time-correlated synchronization and synchronism. Time dependent desynchronization...
